Researchers discover molecular light switch in photoreceptor cells

How our eyes detect and respond to changes in light intensity is determined by specialized cells in the eye called photoreceptors. In addition to converting light into electrical signals, effectively allowing us to see, rod-shaped ...

A protein that pulls the brake on nerve growth

During embryonic development, nerve cells form long, thin extensions that wire up the complex network of the brain. Scientists from the German Center for Neurodegenerative Diseases (DZNE) in Bonn have now identified a protein ...

How cells protect themselves from mitochondrial defects

Cells need powerhouses known as mitochondria to utilize the energy stored in our food. Most of the proteins required for this powerhouse function are encoded in the nucleus and transported into the mitochondria after they ...
